Merge branch 'bc/object-id'
Conversion from uchar[20] to struct object_id continues. * bc/object-id: (25 commits) refs/files-backend: convert static functions to object_id refs: convert read_raw_ref backends to struct object_id refs: convert peel_object to struct object_id refs: convert resolve_ref_unsafe to struct object_id worktree: convert struct worktree to object_id refs: convert resolve_gitlink_ref to struct object_id Convert remaining callers of resolve_gitlink_ref to object_id sha1_file: convert index_path and index_fd to struct object_id refs: convert reflog_expire parameter to struct object_id refs: convert read_ref_at to struct object_id refs: convert peel_ref to struct object_id builtin/pack-objects: convert to struct object_id pack-bitmap: convert traverse_bitmap_commit_list to object_id refs: convert dwim_log to struct object_id builtin/reflog: convert remaining unsigned char uses to object_id refs: convert dwim_ref and expand_ref to struct object_id refs: convert read_ref and read_ref_full to object_id refs: convert resolve_refdup and refs_resolve_refdup to struct object_id Convert check_connected to use struct object_id refs: update ref transactions to use struct object_id ...
